Tasting impressions #59: Light APA (mini-cask)

January 25, 2014 Comments off

APA ended at 4.3 per cent abv. The looks:

Aroma is fruity citrus. Mouthfeel is almost full, soft and round. Initial taste is bitter hops, then malts, and in the finish dry citrus and slight grapefruit. Still very balanced with good drinkability. Half a teaspoon of gypsum seems just about right. Because of the mouthfeel the beer seems bigger than it is and it could be that I’ve stumbled upon a very good mash schedule. Last summer I went off grapefruity ales which seemed to be everywhere around GBBF time but this one is not that bad.

Brew #62: Kohatu Jade Hop Burst Pale Ale

January 21, 2014 Comments off

Brewed to order, specs given were: golden, no hop bitterness, less than 5 per cent abv, fruity and tropical. I left the hops stand for 30 minutes after the boil-off, obviously in real life this will increase the IBU’s but I keep assuming zero impact on paper.

Mash efficiency is getting ridiculously high, 32 litres at OG 1042 after rinsing, 4.665kg at 304.5 degrees litre makes 95 per cent. Could this be due to acidulated malt? A few extra litres at intended gravity won’t hurt…

Kohatu had no aroma at all when taken out from the vacuum foil packet – we’ll see.

Brew #61: Pacific Jade Single Hop Pale Ale

January 16, 2014 Comments off

I intend to brew quite a few single hop beers this year: Bramling Cross, East Kent Goldings, Citra, Chinook and Pacific Gem to start with.

29.5 litres coming to the boil at 1046 gravity, 4.85kg of grist, average degrees of litre 307.6 spells 91 per cent mash efficiency. Bang on 24 litres into the fermentor at 1050 – 80 per cent brewhouse efficiency.

Brew #60: Box Hill Bitter

January 10, 2014 Comments off

Brett_The_Stonebreaker

Practically the same grist as with the previous beer, scaled up and some chocolate malt added for colour adjustment. Cascade hops for aroma and grapefruity freshness.

A spanner into the works – found 20g of Nelson Sauvin un-accounted for while taking the hops out of the freezer, the aroma was still very lemony. Although NS has the most lemony smell and aroma I’ve encountered, it doesn’t show in the finished beer as such.

22g of Magnum hops looked very little but hopefully they were just compressed tighter.

What I’m trying to brew here is a beer that when first seen makes one go “another boring brown beer” but when tasted the aromas from Cascade and NS surprise.

Overshot the gravity by one point. Mash efficiency 85 per cent.

I really like this mash schedule, 45 minutes to go and the wort is already super bright.

Brewing Plans for 2014

January 5, 2014 Comments off

No Belgian yeast. No porters or stouts. One hefeweizen to use up the yeast. Something with rye and rauch malts which I bought last year and have no idea what to do with, yet. Not many brews over 1050 OG.

A single hop series: 8% munich, 3% wheat, 3-5% caramel/crystal malts (carared, caramunich, etc), rest pale ale (or pilsner). Chocolate/black for colour adjustment. EKG, Bram X, Citra, Chinook, Pacific Jade and Gem, Kohatu (this will be low-ibu hop-burst). Single hop beers often are quite one-dimensional but I aim to minimise alcohol tax paid this year and figuring out hop combos takes too much time. I’m trying to save one or two bottles of each till December and have a review on what works and what doesn’t.

Brewing starts today with a light APA, and I’ll be mostly using 5L mini-casks and swing-tops rest of the year.

Tasting impressions #53: Christmas Spiced Ale

January 1, 2014 Comments off

The Christmas beer ended at 7 per cent abv. Bright reddish mahogany copper:

OLYMPUS DIGITAL CAMERA

I’ve gone off Belgian yeast so I used S04 instead, looks like I’ve had enough of spices in the beer too. Aroma is boozy cardamom. Mouthfeel is light and sessionable, dry. Taste is not boozy at all, some crispiness from the hops, very drinkable if I liked those spices, but for me, a step too far. Sugars used really dried and thinned the beer out, not a malty beer. A flavour experiment gone horribly wrong but I’ll get back to this beer in a year’s time to see if the cardamom has eased up a bit.
